This page shows a simulation of the 100000 kt nuclear bomb (100000 kt) detonated over Tehran, Iran. The map displays the estimated fireball, the zones of heavy, moderate and light blast damage, thermal radiation and ionizing radiation.

100 megatons was the design yield of the Soviet AN602 — the Tsar Bomba — before its final stage was throttled back to 50 for the 1961 test. No weapon of this size was ever deployed: the bomb weighed 27 tonnes, no missile could lift it, and the arms race moved towards many smaller warheads instead. This scenario is therefore a physical ceiling, not a military one. The rings are enormous: a fireball about 12 km across, total destruction (20 psi) to roughly 13 km, collapse of houses (5 psi) to about 32 km, third-degree burns on exposed skin to about 75 km in clear weather, and broken windows (1 psi) out to about 100 km.
What that means in Tehran
Centred on the Grand Bazaar, the 13 km zone of total destruction covers the whole of Tehran from Tajrish at the foot of the Alborz to Rey in the south, including Mehrabad Airport. The 32 km collapse ring takes in Karaj's eastern districts, Eslamshahr, Pakdasht and Shahriar — about 12 million people. Burns to 75 km reach Karaj, Varamin, Imam Khomeini International Airport, Damavand and the Alborz ridge; the 100 km ring of broken windows covers the Tehran–Karaj corridor, Qazvin's approaches and Garmsar. The Alborz mountains to the north would shield the Caspian coast completely. Compare with the 1.2-megaton B83 scenario.
